Ranker Video Inside The Horrifying And Lethal Experiments Of Japan's Military Unit 731

In World War Two, Japan created a top secret project named Unit 731 which sought to learn more about human physiology. Officially called the Epidemic Prevention and Water Purification Department of the Kwantung Army, Unit 731's methods were completely unethical - and that's putting it lightly. Brutal human experimentations were conducted in Unit 731 that resemble things straight out of a horror movie. It shocks the mind to think that these experiments really happened, but indeed they did.

Japan committed war crimes throughout WWII that are cruel and horrifying. They used grisly torture methods on countless victims that ranged from bamboo torture to cannibalism. However, the worst methods occurred in Unit 731. Located in Manchuria, most of the test subjects for Unit 731 were Chinese.

By the end of the war, as surrender became imminent, the Japanese involved with Unit 731 attempted to destroy all evidence of the unspeakable crimes they committed. Unlike their Nazi counterparts, the mad scientists running Unit 731 were never punished for their morbid human experimentation. It would be many years before witnesses started speaking out about the unit, and only now does the public understand what really went on there.

Human test subjects in Unit 731 were strapped down to operating tables and then dissected while still living without any anesthetic. Organs were removed and reattached in strange ways. Like a scene out of The Human Centipede, the stomach would be removed and the esophagus would be attached directly to the lower intestines. Pieces of lungs and other tissue would be cut out while the doctors observed the subject who was usually screaming in agony. This continued until the subject died, at which point a new one would be rolled in for examination.

Anthrax, cholera, and other pathogens were "studied" by forcibly infecting victims while scientists watched. One of the main diseases they experimented with was the bubonic plague. The Japanese were trying to find a way to weaponize the sickness by using infected fleas and various delivery systems. The plague bombs they developed were used to infect Chinese cities, with varying degrees of effectiveness.

Doctors in Unit 731 hacked the limbs off their human test subjects just to see what would happen. They would watch people bleed out to calculate how long it took. All of these amputations were performed without anesthesia, so the victim felt everything and was fully aware during the operations. Sometimes, severed limbs were even reattached to other parts of the person's body.

As a diver goes deeper into the ocean, they have to regulate the increased pressure on their bodies. Now think about that pressure increasing until the point where the person's eyes pop out of their sockets. That is what these doctors actually did to people at Unit 731. They locked human test subjects into high pressure chambers and watched as unbearable pressure literally crushed people.
